Changes for version 0.47 - 2023-03-21

    • Also dump the mortals list to the dumpfile
    • Use mro_get_linear_isa() to perform the package helper walk on objects rather than reïmplementing our own bad DFS
    • Delete the now-unused legacy helper API support (RT147233, RT147085, RT145110)


write a heap dump file for later analysis
give XS modules extensions for memory dumping
